The specific embodiment

According to several aspects of the present invention, Fig. 1 and Fig. 2 have illustrated also can utilize at sole to have the shoes acquisition surfer of roller and multiple attitude and the posture that the slide plate person can present, and these rollers are particularly suitable for rolling along the direction that is different from direction of travel.For example, Fig. 1 has shown the user 10 slippery along the concrete pavement, and this user's pin is approximately perpendicular to its direction of motion.Shoes 14 have rolling member 16 in the arch region of its sole, thereby can allow the user to pass through its weight of the direct balance of rolling member, so that realize transverse movement.Best, exceed rolling member 16, in the loe zone of flexible sole, have enough spaces, to allow the user under the situation that does not engage roller, utilize its loe zone to run or walk.It is used in and skips to the surfing posture that is on the roller and can run when beginning before the continuous motion carrying out.In some cases, roller can allow along curb edge, pavement 18 (as shown in Figure 2) or the guide rail or the balustrade that tilt carry out the surfing type motion.

At first referring to the embodiment shown in Fig. 3-5, shoes 20 have a top 22 and a sole 24.Because suitable form arbitrarily known in the art can be adopted in the top 22 of footwear, therefore, needn't not be described too in detail.Top 22 can extend upward to cover wearer's ankle-joint (as illustrated), perhaps can adopt the form of downside otch.As selectable scheme, top 22 extends upwardly to wearer's diseased portion with the form of boots, and top 22 can adopt flexible material maybe can adopt hard form (for example employed form in ski boots and ice skate shell).Equally.Sole 24 can be flexible or hard according to purposes.In a most preferred embodiment, sole 24 forms by flexible synthetic rubber is molded, and has 26, one arch region 28 of a front area and a heel region 30.Cover front area 26 flexible of the toe of pin and sole spherical portion and forwardly the flexibility of the transition portion between zone 26 and the arch region 28 can make sole during normal walking and during " tiptoe walking " (during this period, the wearer only utilizes the front portion walking of its pin, promptly is called " tiptoe walking " by children) bending.

A cylindrical roller 32 is installed in the inner chamber 34 in arch region 28.Roller 32 rotates around a pivot pin 36, and this pivot pin 36 is along the longitudinal extension of shoes, so that roller 32 can freely rotate as shown in Figure 4.In this view, the length of roller 32 only is about 1.0 inches (25 millimeters), and diameter is about 1.25 inches (32 millimeters), and has cylindrical outer surface.The example of other roller structure is as described below.Stiff shaft is installed cup-shaped seat 38 or other supporting member inserted mode system in sole 24, so that the fixedly mounting structure of pivot pin 36 to be provided releasably.The end of pivot pin 36 is entrapped in the respective slot of cup-shaped 38 front and back edges, and by extract roller 32 out from its inner chamber, the end of pivot pin 36 is got loose from its groove.Therefore, the wearer just can easily remove roller 32 under the situation of not using hand-operated tools and needn't taking off one's shoes.

As Fig. 3 and shown in Figure 4, the outer surface of roller 32 extends below the foot of sole 24, so that the wearer can make roller 32 engage smooth area supported (as the pavement), can not engage any other parts of sole simultaneously.In addition, as shown in Figure 4, the lateral edge of cutting sth. askew or otherwise excising sole 24 is so that when any inclination that makes footwear on roller 32 is turned over, can provide terrain clearance.Preferably cut sth. askew sole so that its along at least one direction have about at least 10 the degree tilt angle theta, and should fully bury roller underground so as its only have be not more than about 0.5 inch (13 millimeters) below the sole surface of lower side expose the height ' h '.

In the embodiment of Fig. 5 A and 5B, bearing pin is installed cup-shaped seat 38a and is had four bearing pins and 40, one groups of grooves are installed in front and back edge, so that with the side rolling type cover orientation of Fig. 5 A roller 32 is installed, and other one group at the lateral edges place, so that roller 32 is installed along the rotating direction forward shown in Fig. 5 B.Equally, not only can remove roller 32 easily for normal walking, and can also rapidly roller 32 be clamped with the orientation shown in arbitrary in place, thereby allow the wearer to select to be formed for to skate or the shoes of slide plate pattern.

In the embodiment shown in Fig. 6 and 7, shoes 20a has a hourglass shape roller 42 that is arranged in its arch region, and its maximum outside diameter is about 2.0 inches (51 millimeters), and its mid-diameter is about 1.0 inches (25 millimeters).By its this shape, roller 42 defines a central groove 44, and it is used to receive the bearing-surface structure of a horizontal expansion, as curb edge, pavement (referring to Fig. 2) or the stair railing that is used to carry out extreme sport.When a smooth area supported rolls, roller 42 only engages described surface at two 46 place, spaced-apart maximum diameter district, thereby less rolling contact area and corresponding resistance to rolling is provided, for stable, can also provides long contact range " L " simultaneously.In this case, the scope of vertically rolling " L " is about 2.75 inches (70 millimeters), or is about 25% of the whole length of sole 24a.When shoes longitudinally tilt when contacting with ground with an end that only makes roller, can provide turning efficiency in the curvature shown in the view of the rolling surface of the roller 42 at the place, two ends that exceeds rolling scope " L ".

Another of this embodiment is characterised in that: the pivot pin supporting structure 38a that is embedded among the sole 24a defines many group bearing pin receivers 40, these bearing pin receivers have the axle that is provided with different angles, thereby allow any one position in three diverse locations of roller 42 insertions.Central position shown in the figure, roller 42 are only rotated around the longitudinal axis consistent with normal direction of travel " D " 170, so that the user can be slippery on side direction fully.At All Other Times, the user may wish along slippery with the direction of pavement direction slight inclination.If this occurs, the user then can extract roller 42 out from its middle position rapidly, and is inserted into a position in other two positions again, and the axis of rolling departs from vertically with the angle α of about 15 degree simultaneously.In order to realize slide plate stability, wish the roller 42 of footwear front portion is arranged on the oblique position, make the roller at the rear portion of footwear be in central position simultaneously.

For more stable, one or two footwear can be equipped with two rollers that separate along the shoes width.For example, Fig. 8 and 9 has shown a kind of like this footwear, and it has two rollers 42 in the arch region that is installed in parallel in sole.In this case, two rollers 42 make their drop-center 44 aim at around the rotation that parallels to the axis along the shoes longitudinal extension simultaneously.Embodiment as mentioned above is the same, and roller 42 can be removed, so that walk or run.Roller is at the some place kiss the earth along rolling-operation direction separation " X ", thereby can strengthen the stability of each footwear.This is between the long-time operating period, and reducing the inner thighs tense situation is particular importance.Best, described interval " X " is about at least 2.0 inches (51 millimeters).

Footwear shown in Figure 10-12 has four rolling members 48 that are arranged on place, four angles of rectangle.Two rollers 48 are set in parallel in the heel area of shoes, and two other roller 48 then is set in parallel in the positive front portion of the arch region of footwear, so that the graphic structure of roller can surround arch region.Because the ground contact point limits and has surrounded length L ₁About 3.0 inches (76 millimeters), width W ₁The broad plane domain of about 2.0 inches (51 millimeters), therefore, this structure of roller can provide advantages of excellent stability.Each roller 48 all rotates around a longitudinal axis, and has the drum shape, so that only realize the contact of rolling by trailing wheel or front-wheel, the curvature of described drum allows to realize certain turning to by shoes are tilted forward or backward.

Also can design other side rolling type cover roller structure.For example, Figure 13 and 14 has shown a kind of like this shoes, and it has the four rolling of arranging with bias structure 48, and their four ground contact points define the tetragonal bight of plane parallel.It allows to use the roller with big rolling diameter, makes horizontal spacing W simultaneously ₂Little when being arranged side by side roller.Roller 48 can adopt and be easy to the installation form dismantled for walking, as mentioned above, perhaps as shown in the figure, can be fixedly mounted in the sole so that only as roller shoe.Preferably forward rollers 48 is mounted to the toe section of shoes distance enough far, walks so that can realize tiptoe.

Also can make and sidewinder parts 48 and combine, so that realize side rolling and rotation with arch rollers or sledge plate.Figure 15 and 16 has shown a kind of like this shoes, and it has four roller structures of shoes among Figure 10, but between front and rear rolling wheel 48, also is provided with a rotation roller 50 in the arch region of sole.The degree that roller 48 stretches out from sole is greater than the degree of stretching out of rotation roller 50, so that for side rolling, and roller 48 ground-engagings only.But the user can skip to from the mode of side rolling on the guide rail, so that the guide rail in the part 51 that reduces by the diameter that is contained in rotation roller central authorities relies on arch rollers 50 to rotate.In order to walk or in order to change, by extracting the front end of each roller shaft in the corresponding recesses from supporting member 38b out, and an other end that makes axle tilt and to leave sole and from the corresponding socket of supporting member, to extract described axle out subsequently, can remove each

roller

48,50 among this embodiment with this.

As a kind of selectable scheme of rotation roller, shown in Figure 17 and 18, can use a rotor plate 52, this plate is embedded in the sole along the center line of footwear.Rotor plate 52 has one and is used to hold guide rail or analog and along the spill middle body of its slip.In this certain embodiments, shoes also are equipped with slide plate 54, and these slide plates are overlapping in the side of the arch region of shoes and sole, so that combine guide rail of interlock with rotor plate 52 in order to carry out certain type games.

In the another kind of quadrangle roller arrangement shown in Figure 19 and 20, four elongated spill rollers 50 are arranged to two parallel row, and two rollers are in heel area, and two rollers are in the front portion of arch region.These rollers provide the ground contact point of eight separation together, and on these contact points, shoes can roll with landscape mode, and these rollers define two independent rotation grooves together.

Above embodiment has been described as has the rolling member that is fixed on the supporting member (these supporting members forever are embedded in the footwear sole).In other cases, supporting member can be removed.For example, Figure 21-23 has shown a kind of shoes with two heel rolling members 48, and these rolling members 32 can expose so that roll (Figure 22 and 23), can readjust (Figure 21) in order to walk subsequently.Roller 48 rolls around parallel pivot pin 36, and the end of these pivot pins is fixedly mounted in the both sides of a detachable roller cap 56.If be arranged on (Figure 22) in the heel inner chamber 58 in the inside mode of blind end, then cover 56 pair rollers 56 and position, so that their rolling surface extends below the sole surface around the shoes, thereby can roll on the ground.In order to walk or to run, can remove lid with hand, and it be inserted in the inner chamber 58 again in the outside mode of blind end, thus complete closed and protect roller 48, and make and cover 56 the lower surface and the bottom sole surface in alignment of shoes.A slit (not shown) can be set so that utilize one piece of coin or key just can make roller cap jump out sole.Though shown two heel rollers, other structure can comprise a heel rollers, a heel rollers that combines with the toe roller or one or more arch rollers.The lid of a roller can adopt rectangular in form or other symmetrical footprint, so that in roll mode, can be arranged on lid in the sole or pair roller positions so that carry out side rolling or carry out the rolling of forward " roller-skating pattern ".

For walking mode, also can design other device shoe rolling is reorientated.For example, shoes shown in Figure 24-27 have heel rollers and the toe roller that has pivot pin, these pivot pins can snap in one group of groove 40 among the mounting cover 38c so that in order to carry out lateral wheel to roll these axles are positioned (Figure 26 and 27), and the wheel rolling surface extends in the bottom sole lower face.In order to walk, the user extracts pivot pin out from the groove group, make their rotate 180 degree and they are snapped fits in the second group of cup-shaped seat of the installation in groove 38c (Figure 24 and Figure 25), the degree of depth of described second group of groove is greater than first group of groove, so that make roller be in the lower surface top of sole fully.This mounting means is applicable to the structure and the combination of various rollers.

Various roller structures can comprise some examples that Figure 28 A-28H is shown.At first referring to Figure 28 A, roller 42 has a rolling surface 60, and this surface is formed by a kind of low-friction material (being preferably foundryman's fever curable polyurethane or thermoplasticity injection molding polyurethane).Suitable thermosetting resin comprises methylene diisocyanate (MDI), as Uniroyal B836MDI and toluene di-isocyanate(TDI) (TDI).Other suitable material comprises polyethers or polyesters polyalcohol or rubber.As in U.S. Patent No. 5,829, disclose in 757 like that, can in a rolling surface, be used in combination material with different hardness and frictional behavior, this patent documentation can be in this application with reference to use as proved absolutely in the past.

The low friction rolling surfacing of casting on a rigid core 62 of making by metal or plastics, this rigid core has the end vestibule, be pressed into the outer ring of rolling element bearing (as ball bearing 64) in these vestibules, these bearings allow core body 62 and low-friction material 62 to rotate around pivot pin 36.The inner ring of bearing 64 retrains pivot pin 36 as shown in the figure vertically.Best, when bearing or rolling surface wearing and tearing, the whole assembly shown in the replacing.As above according to Fig. 6 described, roller 42 has the bulb projection ends 46 that a spill middle body 44 and two define two ground contact points.The roller 66 of Figure 28 B has cylinder-shaped end 68 on the one hand, and these cylinder-shaped ends provide wideer ground contact and can not provide turning efficiency when tilting.Replace the one rolling member, as the roller structure of Figure 28 C, the parts that can laterally rotate independently limit rolling surface.In this structure, two convex rollers of being made by low-friction material 48 are rotated on the bearing 74 on central recessed roller 70 any sides, described roller 70 can be around the pivot pin 36a independent rotation on the lining 72.The rolling surface of three rolling members all is similar to the shape of roller 42 among Figure 28 A, but spill roller 70 can adopt different materials, compares as adopting with spill roller 48, can form the material of bigger rolling friction.Shown in Figure 28 D, the outer surface of middle rolling member 70a also can be for cylindrical.

As mentioned above, barrel-shaped or convex rolling member can be used for tilting to provide the control of rotating direction or turning to by the rolling axis that makes roller.Figure 28 E and 28F have shown the structure of these two kinds of rollers.In Figure 28 E, elongated roller 74 has the basic structure identical with roller 42 among Figure 28 A, and both differences are: the outside, low-friction material 60a have been molded as and have the convex outer shape, and had maximum gauge at the middle part of roller.In order to turn to, for example by making shoes, thereby pivot pin 36 is tilted in having the plane of described section with respect to ground inclination so that engage in the middle a side or the outer surface of the roller on the opposite side.Though shown in Figure 28 F, utilize two independent rolling convex parts 48 that are installed on the same axis, similar effect obtained, but it can strengthen lateral stability to a certain extent.

What should emphasize is: the outer surface of rolling member is tapered so that at parts when its axle rotates, can produce continuously along rotating direction and change.In Figure 28 G, the rolling surface of the end 76 of roller 78 is along the taper seat setting, so that can roll along the direction of turning left.Can two described rolling members 78 be set end to end along the longitudinal centre line of sole, the big end that makes them simultaneously toward each other, thereby can tilt to realize turn to by shoes.Along direction forward, utilize sole parallel to the ground, shoes will rely on the big end of two of roller to roll.In Figure 28 H, in order to have similar effect,

tapered roller

80a and 80b have the outer surface that is arranged in the same conical extension.

For example, utilize suitable installed part that rolling member is installed on the sole, also can realize turning to control by in the bearing pin mounting structure of sole, adding an amount of compliance.

More the maneuverability of Ci Jiing has a roller or wheel installed part, and it can respond and turn to input, causes variation along the orientation of wheel shaft.For example, shoes 82 are equipped with a type and the similar holoaxial roll wheel assembly 84 of roll wheel assembly that uses in pairs usually among Figure 29-31 on slide plate.The bottom 86 of roll wheel assembly 84 is firmly-fixed on the sole of shoe's arch region.Roll wheel assembly 84 has an axle 88, and the roller 90 of two substantial cylindrical that structure is similar to the slide plate roller is around this independent rotation.As shown in figure 31, axle 88 has a pin 92, and it is contained in 86 the socket of bottom and can free rotates in socket.By the tilting shoulder bolt 94 between two
